Keryx Engineering (first-party) states that the client checks the portable receipt's canonical SHA-256 digest and binds it to the original question and returned answer. According to Keryx Engineering, this is supported by the client performing that digest check and binding, and receipt snapshots being archived by digest, with reconciliation possibly producing a different snapshot without erasing the older one. The source does not describe any further supporting mechanism or independent verification beyond these first-party statements.

Sufficiency

Sub-claim "What supports that claim according to Keryx Engineering?": 80% covered by S1

Sufficiency

S1 (Keryx Engineering first-party) directly addresses the first sub-claim: it states that the service receipt reports evidence coverage separately, and that a completed job does not mean the answer was adequately supported. This is the specific claim about evidence preserved with a Keryx research receipt. For the second sub-claim, S1 provides supporting basis: the receipt's canonical SHA-256 digest is checked and bound to the original question and returned answer, receipt snapshots are archived by digest, and reconciliation may produce a different snapshot without erasing the older one. S2 is unrelated to Keryx receipts and provides no support.

Final check — "What specific claim does Keryx Engineering make about eviden…": 100% assessed by S1

Sufficiency

Final check — "What supports that claim according to Keryx Engineering?": 100% assessed by S1

Sufficiency

Final coverage assessment — The first sub-claim asks what specific claim Keryx Engineering makes about evidence preserved with a Keryx research receipt. S1 directly states that the service receipt reports evidence coverage separately, and that a completed job does not mean the answer was adequately supported. This is a specific first-party claim about evidence preserved/reported with the receipt. The second sub-claim asks what supports that claim according to Keryx Engineering. S1 supports the claim by describing the receipt's canonical SHA-256 digest binding to the original question and returned answer, archived receipt snapshots by digest, and the separation of payment evidence from content delivery. These passages directly answer both requested parts. S2 is unrelated and provides no support.
